Show HN: I made a simple portfolio performance calculator and it seems to work Hello, this is my first project! I used nothing but free web tools. And it seems to work. I couldn't find a simple portfolio performance tool on the web, where I could just paste cash inflows, outflows and current value of my portfolio and get the portfolio performance calculated. Everything I found was in some way cumbersome and cluttered with ads. I used Perplexity for the coding and Codeberg for the hosting. I verified the output manually for some examples and all seems fine. Maybe it is useful for others too. If anyone can spot a problem in this small project, I would be very grateful to hear about it. https://bit.ly/3L7E8mz October 25, 2025 at 08:27AM
